McShane will play Hellboy’s adoptive father, Professor Broom.

Ian McShane, currently starring on Starz’s American Gods, is joining David Harbour in Lionsgate and Millennium’s Hellboy reboot.

Harbour is toplining as the demonic hero from the Mike Mignola comic books in a new feature, formerly titled Hellboy: Rise of the Blood Queen, that Neil Marshall, the horror director who broke out with The Descent and won raves for his work on Game of Thrones, is on board to helm.

The new story sees the hero squaring off against a medieval sorceress who seeks to destroy humankind.

McShane will play Hellboy’s adoptive father, Professor Broom.

The project is eyeing a September start and will shoot in the U.K. and Bulgaria.

Larry Gordon and Lloyd Levin are producing along with Mike Richardson of Dark Horse Entertainment.

McShane, who won a Golden Globe for his starring role on HBO's Deadwood, has also been winning praise for his work on American Gods, in which he plays Mr. Wednesday, an enigmatic god from the Norse myths. He also has been a steady presence in the John Wick movies, where he plays the steely-eyed owner of the boutique hotel that caters to assassins.

The Hellboy casting keeps the actor in the Lionsgate family as the studio is also behind the Wick franchise and owns Starz, the maker of American Gods.
